√(32 cm2) = 4√2 cm ≈ 5.66 cm
The sidelength of a square is the square root of its area, and its perimeter is four time this. 4 x sqrt(9 cm2) = 12 centimetres.
cm2 square is a measure of hyper volume in 4-dimensional space.
Given: V = 104 cm3, h = 8 cm Find: Area Solution: Since V = Bh, where B is the area of the base, and h is the height of a prism, then B = V/h substitute the given values: B = 104 cm3/8 cm B = 13 cm2, which tells us that the length side of the square base equals square root of 13. The surface area of a prism = L.A. + 2B, where L.A. is the lateral area of the prism. L.A. = pH, where p is the perimeter of the base. Since p = 4(square root of 13) cm, h = 8cm, and B = 13 cm2, we have: Surface Area = pH + 2B = [4(square root of 13) cm](8 cm) + 2(13 cm2) = 115.38 cm2 + 26 cm2 = 141 cm2 Thus, the surface area of the prism is approximately 141 cm2.
since A=lengthxwidth and in a square all sides are equal you would take the square root of 256 which is 16 so each side is 16cm
